Django security releases issued: 1.11.5 and 1.10.8


Posted by Tim Graham on septembre 5, 2017

In accordance with our security release policy, the Django team is
issuing Django 1.11.5 and Django 1.10.8. These release addresses the
security issue detailed below. We encourage all users of Django to
upgrade as soon as possible.

CVE-2017-12794: Possible XSS in traceback section of technical 500
debug page

In older versions, HTML autoescaping was disabled in a portion of the
template for the technical 500 debug page. Given the right
circumstances, this allowed a cross-site scripting attack. This
vulnerability shouldn't affect most production sites since you
shouldn't run with DEBUG = True (which makes this page accessible) in
your production settings.


Thanks Charles Bideau for reporting this issue.


Affected supported versions

Django master development branch
Django 1.11
Django 1.10
Per our supported versions policy, Django 1.9 is no longer supported.
Django 1.8 is unaffected.


Resolution

Patches to resolve the issues have been applied to Django's master
development branch and the 1.11 and 1.10 release branches. The patches
may be obtained from the following changesets:

On the development master branch
On the 1.11 release branch
On the 1.10 release branch

The following releases have been issued:

Django 1.11.5 (download Django 1.11.5 | 1.11.5 checksums)

The PGP key ID used for these releases is Tim Graham: 1E8ABDC773EDE252.


General notes regarding security reporting

As always, we ask that potential security issues be reported via
private email to security@djangoproject.com, and not via Django's Trac
